05: 配置yum源

1.1 将镜像复制到本地创建yum源

　　　　1、将准备好的系统镜像放到指定的目录，本次目录指定在：/dawnfs/sourcecode
　　　　2、创建挂载目录：mkdir /mnt/yum
　　　　3、挂载镜像： mount -o loop /dawnfs/sourcecode/rhel-server-6.2-x86_64-dvd.iso /mnt/yum挂载完成后，使用 df -h来检查挂载是否成功：

                          

　　　　4、修改/etc/yum.repos.d/local.repo文件

[local]
name = Red Hat Yum Name
baseurl=file:///aaa/CentOS-7.3-x86_64-DVD-1611
enabled=1
gpgcheck=0

　　　　ps:原文件中enabled=0,gpgcheck=1.修改成enable=1,gpgcheck=0。否则输入 yum grouplist 命令时会报错
　　　　5、清除原来的yum: yum clean all
　　　　6、检查软件列表：yum list
　　　　7、查看yum组：yum grouplist
　　　　8、安装yum组，以安装Desktop为例： yum install -y "Desktop"

 1.2 将windows共享挂载到centos 7.3中并配置yum源

　　1、临时挂载windows共享

　　　　　　mount.cifs  //1.1.1.100/share  /aaa  -o  user=tom,pass=1

　　2、配置yum源文件

[local]
name = Red Hat Yum Name
baseurl=file:///aaa/CentOS-7.3-x86_64-DVD-1611
enabled=1
gpgcheck=0

1.3 配置centos网路yum源

 　　cd /etc/yum.repos.d

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
